KARL SOI'IULZE, OF HANOVER, GERMANY.

PIANO-PEDAL.

SPECIFICATION forming part of Letters Patent No. 572,316, dated December1, 1896.

Application filed November 25, 1895. Serial No. 569,999. (No model.)Patented in Austria June 19, 1894, No. 44/2526.

To all whom it may concern.-

Be it known that I, KARL SOHULZE, musicmaster, a citizen of the Kingdomof Prussia, and a resident of Hanover, in the Kingdom of Prussia andGerman Empire, have invented certain new and useful Improvements inPiano-Pedals, (for which I obtained a patent in Austria June 19, 1894:,N0. 44/2,526,) of which the following is a specification.

The object of my invention is to provide an improved adjustablepiano-pedal which will adapt them for use by persons of different sizes,from small-sized children to the tallest grown persons.

Such devices have heretofore been more or less complicated and haveconsisted chiefly in separate attachments more or less complicated andhaving interposed boards or footstools connected with the proper pedals.

My invention consists in a pedal lever shaped in the usual way and madeof two separable sections, one of which has a squared hole through itsunderlapping flange, and the other of said sections has a square barsecured at right angles thereto to pass through the square hole in theunderlying flange, and a set-screw which passes through one of saidsections and engages with the square bar to adjust one section upon theother, as will hereinafter appear.

In the accompanying drawings, which illustrate my invention, Figure 1 isa perspective view of an adjustable piano-pedal with the two sectionsbrought together in the same plane to adapt the pedal to suit persons ofmedium height; Fig. 2, a similar view of said pedal with the adjustablesection raised above the lever-section to adapt it for the use ofshorter persons, and Fig. 3 a similar view of the pedal with theadjustable section depressed or pendent from the levcr-section to suitextra-tall persons.

The pedal-lever A has a depressed underlapping portion a, having asquared hole a, passing vertically through the said underlying portiona, and a side flange into which is fitted a clamping-screw D, whichextends under the portion a of the lever and engages with notches E in asquare bar B, secured at one end and at right angles to the adjustablesection 0 of the pedal. The bar 13 is numbered l to 10, each numberhaving a corresponding notch E therein to receive the end of theclamping-screwD and thus effectively prevent the barB from slipping pastthe screw D when the latter has been adjusted. This is so easily donethat a child may readily fix the pedal at the number required and thusadapt it to be reached conveniently from the stool by the person forwhom the adjustment has been made.

The foot-rest or adjustable section 0, with its square bar 13, may beturned up, as shown in Fig. 3, with the said bar passing through thehole in the portion a and secured thereto by the set-screw D, thusadapting the adjustable section for use by adults.

The construction herein shown is simple, strong, inexpensive, andeasilyadjusted, even by children, the numbers and corresponding notchesgreatly facilitating the adj ustment.

I claim as my invention and desire to secure by Letters Patent 1. Anadjustable piano pedal, consisting of a lever-section A, having adepressed portion a, an adjustable section 0 and a square bar 13 securedthereto, having a depression in one side thereof and a set-screw Dfitted in the lever-section Ato engage with the depressions of the bar,substantially as described.

2. An adjustable piano-pedal, consisting of a lever-section A, having adepressed portion a, an adjustable section 0, a square bar B securedthereto having a depression in one side thereof and a series of numbersopposite each of said depressions and means for locking the bar 13opposite each of said depressions, substantially as described.

In testimony that I claim the foregoing as my invention I have signed myname in the presence of two subscribing witnesses.

KARL SOHULZE.
